Ed. FPANJEN what causes the pendulum to move toward the front or the rear edge of the plate I! when the a wheel 2 isturn'ed from the position of Fig. 1

;therein so as to turn the bracket until'itfis tight., 1 The bracket i9 is provided'with a yoke 20 which surrounds the bar or post I! and has a set screw 2| therein for engagement with'the bar to hold thebracket in adjustedposition. By adjusting the brackets I8 and I9 longitudinally of' the bar;

toward that of Fig. 3 or Fig. 4.

The means whereby this device is adapted for use as a camber'gauge will next be described.

This comprises a supporting bar 11. having a single laterally extending bracket I8 adjustably or farther away from the end of said bar. We

prefer to provide bracket" with a hole extending transversely therethrough so that a suitable punch, bolt, or the like may be inserted orpost ll, one may adapt this camber gauge including; wheels having a felloeidi ameter of for use] with wheelsof large or smalldiameter,

, about'eleven inches u'p to wheels havinga felloe diameter 01' about twenty-four inches- Of'course,

in event of necessity, the post I! could be. made.

longerin' order to 'span a wheel havinga larger diameter and a "suitable-hole could be made in the post I! for attachment of bracket I 8 so as to make this'device adaptable to wheels having a smaller felloe diameter. However, it labelieved that the present construction is entirely ample for all wheels as now constructed. p

In order to attach the post I! tothe body memher 5, screw I 4 is removed from member ll, thus these members "together.

permitting thismember to'be detached. .The'

post is then applied to the member 5 and screw II is screwed into a suitable'hole in post l1, thus fastening these'two members together. .Other aligning holes are formed near the lowerextremities' of the members 5 and Iland,v a screw 22, corresponding to screw I4, is inserted to bind It will therefore be seen that-when'the ends of the brackets l8 and i9 are set against the felloe and the post I! is turned laterally until the plumb bob 9 points to the zero line, laterally, of plate IS, the post I! will bein a vertical plane transversetothe plane of the wheel and passing through. thecenter thereof. If the nut I6 'is' loosened so as to permit the plate l5 to' be slid along the bar! as far as possible, the plumb bob 9 will be just in line with the inner gauge line of the plate when the bar i1 is vertical. Therefore, when this deviceis. applied to a-wheel, the plumb bob will swing outwardly on the plate l5 and the numberof lines will 'indicate'the number of degrees of camber which the wheel has.

It isbelieved thatfromjthe foregoing description, taken in'connection with the annexed drawing, it 'will be clear that the inclination of the king pin; both laterally and forwardly-backwardly, may be read by means of this implement and in a very simple manner. It will also-be apparent-that the number of degrees of inclination of the plane of the 'wheel from a vertical can be read directly upon the graduated plate.

It is of course. understood that the specific description of structure set forth above maybe graduated plate supported adjacent the lower end of the body member, a rigid pendulum supported from the upperpart of the body member and having an indicating point adjacent the plate to cooperate with the graduations thereon to indicate movementoi' the pendulum relatively there.- to, the plate being graduated to read correctly the'inclination of the king pin of an automobile wheel when the spindle is turned through a deflnite angle about the king pin, and a guard mounted on the body between the plate and the upper part of the body to restrict the movement of the pendulum with respect to the plate butpermit it to have free'movement over the entire surface of the plate.

2. A gauge. for determining king pin andspindle angles comprising a body member having a clamp secured thereto, saidclampbeing adjustably secured to the body member to permit adjustment of the latter with relation to the former in a planesubstantially at a right angle to the;

axisof theispindle'to which secured, and said clamp being attachable" to the spindle nut of an automobile axle,'arms projecting from the body member adjacent its upper and lower ends, a graduated plate supported by thelower arm, and a pendulum suspended from'the upper arm and adapted to swing in close proximity to the graduated face of saidplate, the'plate being graduated to read correctly the inclinationstof. the king pin 01 an automobile wheel when the spindle is.

turned through a definite angle about the king pin as an axis.

3. A structure as defined bylclaim 2 in which the lower arm is provided with a slot and the graduated plate is'provided with a lug fitting in saidslot, said plate and arm being connected'by adjustable means permitting'the plate to be secured invarious adjusted positions with relation to the arm. I

.4. Aking pin inclination gauge comprising a body member adapted to be supported upon an .axle spindle to m'ovetherewith, a rectangularly graduated plate supported adjacent the lower end of the body member, -a pendulum supported from the upper part of the body member and having an indicating point adjacent the plate to cooperate with the graduations thereonto indicate movement of the pendulum relatively thereto, the pendulum comprising a'rod screw-threaded at its lower end anda plumb bob having a screwthreaded aperture in its upperend for connection with the rod, the two being relatively adjustable so that the distance of the plumb bob from the plate may be adjusted as desired.

5. A king pin inclination gauge comprising a body member adapted to be supported upon an axle spindle to move therewith, a rectangularly graduated plate supported adjacentthe lower end of the body member, and a pendulum supported from the upper part of the body member and having an indicating point adjacent the plate to cooperate with the graduations thereon to indicate movement of the pendulum relatively thereto, the plate being graduated-to read correctly the inclinations of aking pin of an automobile wheel when the spindle is turned through a definite angle about the king pin, and the V endulum comprising a mw-mrmedat its lower, end anda plumb bob ha vinga screwthreaded aperture in itsupper end for connection with the rod, the two being relatively adjustable so that the distance 01' theuplumb bob from the plate may be adjusted as desired. 7
